Wahana Estate, which was established by our milling partner in 2005, is the only large, private coffee estate of its kind on the island. It is situated between 1,300 to 1,500 metres in the village of Lae Mungkur, in the Sidikalang district of North Sumatra – an area famous for its coffee due to its ideal climatic conditions, including the highest levels of rainfall in the Lake Toba region.
Wahana Graha Makmur means “Vessels for Great Success”. Accordingly, the Estate’s mission is more than just to produce high quality coffee themselves. They are also committed to improving coffee quality for farmers throughout the region. As an experimental farm, one of their aims is to find varietals that are well-suited to the region’s climate. The estate has established a farmers’ support center which distributes coffee seeds - free of charge - and offers information and advice on farm management, distribution of shade trees, and use of organic fertilizer. Wahana also processes hand-picked, ripe cherries for small growers in the surrounding region.
The estate has planted around 250 hectares with 13 different local and international varietals. These are carefully separated into different lots in order to produce distinct single varietal coffees, including some interesting local Indonesian hybrids - Rasuna, Long Berry, Andong Sari, Toraja, S795 (Jember), Jantung – and more widely known international varietals - Caturra, Catuai, Villa Sachi and Colombia Típica varieties. Each hectare under coffee can support around 2,000 trees - these are evenly spaced at 2m x 2.5m and are shade grown under local Lamtoro trees.
Unusually for Indonesia, much of Wahana’s coffee is fully-washed – using the estate’s new wet milling facility. This was installed in 2009 and can process an impressive 25 metric tonnes of red cherries per hour. The cherries are picked only when fully ripe and are then sorted and graded by hand when they reach the dry mill, before being pulped. The coffee is then fully fermented until the mucilage becomes removable, is fully washed and is then dried on the mill’s extensive patios to 11% humidity.
The Longberry variety is so named due to its appearance, which is long and thin in comparison with other coffee varieties. It is thought to have originated from Ethiopia due to its similarity to Longberry Harrar (a natural mutation of the Typica variety).
In Indonesia, Longberry was initially associated only with Aceh; however, several years ago Wahana Estate brought the coffee to the Lake Toba area as one of Wahana’s experimental varieties.
This coffee is not your typical Indonesian coffee. Clean, soothing & incredibly sweet, a great example of well processed Indonesian coffee. You'll get lots of sticky sweetness of black dates, & sweet potato pie, finish with hints of liquorice. Great coffee to slowly enjoy in the afternoon.
